The real cost of back up
Imagine building and maintaining a perfectly good gas plant and then having it sit around for five whole years “just in case”?
There’s been a wind drought in the last three months in Australia, which meant hydro power had been used more than expected to fill the gap. But wouldn’t you know it, it’s been dry spell for most of the last year in Tasmania too and the dams were getting low. So on June 6th, the Combined Cycle Gas plant at Tamar Valley was set up to run for the first time since 2019.
Back in 2016 the maintenance costs of the keeping the CCGT at Tamar Valley on “30 day” standby was $12 to $24 million a year, depending on who you asked. So the five year cost of gas backup is in the order of $100 million, but those costs will be slapped on the gas plant bill, when really they’re a weather dependent renewables cost. What we need is reliable energy, not random electricity. If energy companies were only paid for reliable dispatchable power, the wind and solar plants would have to build their own “back up […]
Bob Brown’s Foundation protests at the Robbins Island Wind Farm
By Jo Nova
Every day the Greens sound more like Skeptics
Finally, the wheel turns and the Greens start to realize their bedfellows might be the environmental wreckers and industrial profiteers that they thought they were working against. Finally there is a point where the price of “climate action” can be too damn high. And somehow, the ends does not always justify the means.
Make no mistake, Bob Brown was the face of the Greens in Australia for decades. He was in politics for 30 years, and Leader of the Australian Greens. He was Mr Green himself on the Australian scene.
Four years ago he surprised a few people when he spoke out against the idea of putting the largest wind farm in the Southern Hemisphere on remote Robbins Island off NorthWest Tasmania because it would spoil the view and kill birds — something climate skeptics have been saying for years and about nearly every industrial wind park.
Now he’s going further and saying the “free for all” with wind farms must stop. He’s even using the ugly term “profiteers” to describe the Tasmanian government setting up a […]

Greens destroying nature again
Some experts think there may be only 1,000 of these eagles left, our largest bird of prey, and yet in the last 12 years some 272 of them have been killed or injured in the vicinity of Tasmanian wind towers. That’s at least as far as the maintenance crews have noticed, and not that they were specifically looking…
So the number can only go up, and other types of birds are getting the chop too.
The Tasmanian Wedge-tailed eagle has been known to have a wingspan as large as 2.8m (9ft 3in). They mate for life, and a single nest can be 1 – 3 meters across.
Tasmanian wind rush ‘may push eagles to extinction’, says study
By Matthew Denholm, The Australian
Tasmanian wind farms and transmission lines have killed or injured 321 threatened eagles in 12 years, but the real figure is likely far higher, a new study finds.
The peer reviewed study, published in Australian Field Ornithology, uses data from wind farms, TasNetworks and eagle rescuers to identify the death or injury of 272 endangered Tasmanian wedge-tailed […]

A second big Australian “Pumped Hydro” scheme is crashing on economic rocks…
The Marinus Link cable was meant to spark a glorious renewables boom and make Tasmania “The Battery of the Nation”, instead it will cost more than a new advanced coal fired plant, provide no energy at all, and currently even the thought of it is causing chaos. New projects are on hold, factories can’t expand and Tasmania is held hostage to visions of an electricity grid designed to stop storms instead of generate energy.
The Marinus Link is a 255km cable that was supposed to be the second interconnector from Tasmania to the mainland. In theory it would cost $3 billion and carry 1.5GW of electricity. But the costs have blown out to $5.5 billion and the State Premier is balking at the new bill.
However, most of the new wind power projects in the state are awaiting the magic cable before they commit — without it, they can’t reach the real market, which is mainland Australia. But without them, the local grid doesn’t have enough surplus capacity to cover the lean times (or rather, without the cable, they can’t get access to more reliable […]

When does it make sense to build 122 giant industrial turbines that can’t operate for nearly half a year?
The EPA has approved Robbins Island Mega Wind Factory in a remote island off Tasmania that will have to stop working for five months of the year so it doesn’t hurt the Orange-bellied Parrot. It will however be able to kill eagles and other birds for the other seven months of the year.
Green electrons are revered, Orange-bellied parrots are sacred but our way of life is up for grabs. It’s a cult.
This is infrastructure that only works about 30% of the time anyhow, and now will be reduced to something like 17%. The theoretical capacity will be 340MW in the first stage, supposedly growing to 900MW if they can somehow build the extra 170km transmission lines and perhaps get the taxpayer to help build another undersea cable across the Bass Strait. (If the company was going to pay, why was the Tasmanian government spending $20m on the “business case”?)
It will be one of the largest wind factories in the Southern Hemisphere (the biggest being West of Melbourne), but as Tom Quirk showed years ago, when […]
They told us if we stopped driving our cars that global CO2 levels would fall. But after 6 months of the most draconian low carbon diet ever, Cape Grimm Tasmania is still measuring a normal rise in CO2 levels.
Here’s the wild absurdity — Covid restrictions are expected to cut human emissions by 4 – 7% but to reach the Paris Target, we “need” exactly that kind of reduction every single year for the next ten years.
h/t to Chris Gillham again
Carbon dioxide levels over Australia rose even after COVID-19 forced global emissions down. Here’s why
Zoe Loh, Helen Cleaugh, Paul Krummel, Ray Langanfelds, The Conversion
…our measurements show more CO₂ accumulated in the atmosphere between January and July 2020 than during the same period in 2017 or 2018.
Look at the graph (below) of CO2 levels rising on their annual cycle each year.
There was a huge reduction from 2016 to 2017. It’s almost like China built lots of coal power plants, then disassembled them. That, or perhaps CO2 levels are controlled by plankton and have nothing much to do with human activity.
This is terrible news, […]
The Tasmanian Government has just announced they will be “200% renewable” by 2040 — a feat only possible because they have an umbilical cord to hostages in the mainland who have to pay for irrelevant surges in electricity that arrive when they don’t need it. The same hostages will send back fossil powered electricity every week to keep Tasmania running when the wind and sun stop and the water is worth more in the dam than out of it. Not to mention container-ships of GST cash to support the state with the second highest unemployment in the nation.
This is the same state that went 100% renewable for three months in 2015 and launched itself into an electricity crisis. They decommissioned the last fossil fuel power station, just in time to get islanded by a break in their umbilical cable and thence had to order flying squads of diesel generators to keep the lights on at a cost of at least $140m. They also had to restart the same plant they just closed. The state lost half a billion dollars in the crisis — nearly twice the cost of the newish gas plant which had only built in 2009.

The Basslink cable has gone down again, and is expected to be out of action til mid-October. Luckily for Tasmania, the dams are at 45% full. However in Victoria, which sits on one of the largest brown coal reserves in the world, currently prices are hitting $300/MWh every morning and every evening at peak time. This graph below shows 5 minute prices for the last two days in Victoria. Every dollar Victoria saves at lunchtime from solar generation is lost a few hours later, and then some. Though it’s wrong to use the word “saves” at any time of day. The wholesale price of brown coal power for years was $30/MWh, and this below is a wholesale price graph. Even the lunchtime “low prices” are twice as expensive as brown coal which can supply all day, every day and for hundreds of years to come and doesn’t cause voltage surges, frequency instability, or house fires, and doesn’t need backup batteries, demand management schemes, free movie tickets, or dark hospitals.
The AEMO must be counting their lucky stars that this happened at probably the “best” time of year when demand is lower.

After nearly two weeks the ABC carrier pigeons finally brought the news that Bob Brown, former Greens leader, is campaigning against this gigantic wind farm — the $1.6b one in NW Tasmania that wants to be the largest in the Southern Hemisphere. Could it be the ABC doesn’t want to admit they were wrong too, pushing wind power non stop for years?
Look how erratic that wind is — 90% one day, zero the next
Tom Quirk looked at the nearest wind farm to Robbins Island, and it’s a fitful machine (see that graph below). Worse, it fails in synchrony with most wind farms in Australia. Thus exacerbating the unstable, fickle supply of wind energy.
Tom Quirk predicts the demise of another coal plant
Quirk was Deputy Chairman of VENCorp, which managed the transmission and wholesale natural gas market and system planning for the electricity market in Victoria, Australia.
A wind farm on Robbins Island will simply extend the variations in power supplied to the mainland while making no difference to the correlations of wind through the states in the wholesale market. Thus more backup would be required from gas and hydro sources. Loy Yang B […]
Do we need wind farms to save the world or not? Not, says Bob Brown.
Robbins Island, North West Tasmania
People can have sleep and health and their views destroyed, but that didn’t matter til a farmer on a remote island off Tasmania made a deal to build one of the largest wind “farms” in the world.
Graham Lloyd, The Australian
Former Greens leader and veteran activist Bob Brown is campaigning to stop a $1.6 billion wind farm development in Tasmania because it will spoil the view and kill birds.
The proposed Robbins Island wind farm in Tasmania’s northwest will be one of the world’s biggest, with up to 200 towers measuring 270m high from ground to blade tip.
He’s written a letter protesting about the view:
Despite the criticisms levelled at former prime minister Tony Abbott and treasurer Joe Hockey for describing wind turbines as “ugly”, Dr Brown said the Robbins Island plan was, visually, a step too far. “Mariners will see this hairbrush of tall towers from 50km out to sea and elevated landlubbers will see it, like it or not, from greater distances on land,” Dr Brown said. […]
For the last year everyone has been calling Tasmania the “Battery of the Nation” — Turnbull, Hydro Tasmania, government departments, the ever hopeful green press. It’s an official plan. The bright idea is to add “Pumped Hydro Storage” to the large dams already on the island state, boosting the only reliable renewable type of energy. But right now, as far as mainland Australia goes, Tassie is a No-Volt Battery.
Even Hydro Tasmania is calling itself the “Battery of the Nation”
The dirty secret is just how fragile the link is. Not only did it break for six spectacular months in 2016 — leaving the “green” state flying in squads of diesels — but its now quietly out of action again and it’s projected to be out for two months all up. The 290 km undersea cable known as Basslink is the second longest of its type in the world. It broke on 24 March 2018. It is not expected back in action til May 31. It was an accident of routine maintenance at one end.
“The equipment was damaged by a third-party contractor during routine works. There is no damage to the cable itself.”

The fear is palpable
How much fun can you have living in a global experiment? In Australia, peak summer is about to hit in a post-Hazelwood-electricity-grid. There’s a suite of committee reports as summer ramps up. Everyday there’s another Grid story in the press, and a major effort going on to avoid a meltdown. Minister Josh Frydenberg announced today that “we’ve done everything possible to prevent mass blackouts”. Or as he calls it, a repeat of the South Australian Horror Show. Politicians are so afraid of another SA-style-system-black that they are throwing money: The “Snowy Hydro Battery” will be another $2 billion. Whatever. It’s other people’s money.
This is what they are afraid of:
The red bars mean “Reserve Shortfall”. The dark blue matter is “Generation”. The graph covers two years (sorry about the quality) so the two red bursts are summer 2018 and summer 2019.
SA Medium Term Forecast, Outlook, AEMO, Nov 16th 2017, South Australia.
Oddly we are headed for a critical time, but this’s the most recent graph I can find — thanks to Wattclarity — from November 16th, 2017. (Here’s an earlier version from March 2017. and from Dec 2016). Perhaps there is a newer […]
Outback couple build solar farm to prove fringe-of-grid power generation needs
Building a $14 million solar farm is an expensive way to send a message about electricity prices, but Doug and Lyn Scouller said they were left with few options.
In Normanton, 500 kilometres north of Mount Isa in north-west Queensland, the Scoullers built a solar farm big enough to power an area almost twice the size of Tasmania, in a move to prove to stakeholders the benefit of positioning power generation sites at the end of the grid.
In old fashioned terms, the “farm” produces five-megawatts. But yesterday, Tasmania didn’t use 5MW it used 1,072 MegaWatts. So this solar farm would have supplied 0.2% of the houses and businesses on an area “twice the size of Tasmania”. The only Tasmania-sized-areas that would be functioning on 5MW are in the empty desert or the Great Southern Ocean.
And we wonder why some Australians think solar power is a no brainer. If this little farm can supply 120,000 km2, we just need another 60 like it, and we could do the whole continent!
ABC journalists are not good with numbers. If only they had a billion dollars […]
Flinders Island is in the Bass Strait North of Tasmania.
If there is a heaven for renewables, this island should be it. But instead, even on Flinders Island, renewables aren’t cheaper than diesel generators. This is a dismal reality, yet the ABC promotes it as a fantasy poster-isle, interviewing only vested or “no idea” people, asking no critical questions, doing no counter research and telling us renewables will be “more reliable” and implying they are cheaper too. The ABC is a three-million-dollar-a-day advertising outlet for other government agencies. Instead of serving Australians it appears to be there to help shake down the taxpayer.
ABC renewables hype strikes again: Rhiannon Shine reports Flinders Island as a showcase of the brave new renewables world. Let’s translate that spin and see just how pathetic it is. If anywhere was going to be totally renewable, Flinders Island would be it — a first world island, tiny population, massive subsidies, no access to cheap coal or gas power, government support at every level and placed in a handy wind stream known as “the Roaring Forties”. Yeah! This is one of the last places in the first world (short of Antarctic stations) where renewables […]
Greedy Green Hubris gone wrong? It took months of bad choices to achieve this Gold-Star Moment in Bad Management:
Tasmania’s state-owned Hydro-electric power generator could face legal action for damages after admitting it cloud-seeded in or near water catchments the day before disastrous flooding, although heavy rain was forecast.
Tasmania shut their only fossil fuel power plant in August last year, and relied on renewable energy and one sole Basslink electricity cable to mainland Australia. The cable was supposed to be a back up supply but was bringing in 40% of Tasmania’s electricity, and it broke in December. But a green and greedy approach in Tasmania meant that the state had already run its dams down to 26% levels by selling too much electricity to the mainland at high “renewable” subsidized prices. That was a low level at the start of summer, normally a drier season in Tasmania. After the Basslink cable broke, the dam levels fell to a precipitous 13%, so fast that the green state had to bring in diesel generators just to keep the lights on. They also switched back on the Tamar Gas plant in late January. So much for being the “100% […]
Venezuela Shuts down
In a land where energy makes up 25% of their GDP and most of their exports — it takes some management to run out of electricity. Apparently the land of oil needs some fossil fuel generation.
Venezuela to Shut Down for a Week to Cope With Electricity Crisis
The government has rationed electricity and water supplies across the country for months and urged citizens to avoid waste as Venezuela endures a prolonged drought that has slashed output at hydroelectric dams.
The socialist solution? Blame the weather:
The ruling socialists have blamed the shortage on the El Nino weather phenomena and “sabotage” by their political foes, while critics cite a lack of maintenance and poor planning.
And hope for help from heaven:
“We’re hoping, God willing, rains will come,” Maduro said in a national address Saturday. “Look, the saving is more than 40 percent when these measures are taken. We’re reaching a difficult place that we’re trying to manage.”
Looks like Venezuela will be doing its bit for the Paris agreement then.
